In the past, I have used a program called
Homeschool Tracker (HST) to create my high school transcripts. I never had any problem with colleges accepting the transcripts I generated with this software. Although HST creates nice transcripts, it isn't a transcript-only service, and the software I used years ago is not for sale or supported by the company any more. They now offer a yearly subscription for a cloud online service which does just about the same exact thing and is much more expensive than the original software. If you want a place to keep all your records, including lesson plans, attendance, reading lists, etc. and a transcript generator, then HST may be the right thing for you. I have decided to discontinue the HST online service because I don't use many of its features, so it's not worth the price.
